ELECTRICAL ACCUMULATOR.

SPECIFICATION forming part of Letters Patent No. 317,487, dated May 12, 1885. Application filed J nly 5, 1884. (No model.) Patented in France January 27, 1883, No. 153,393.

To aZZ whom it may concern.-

Be it known that we, JULES JOAS BAR- RIER, FERDINAND TOURVIEILLE, and J ULES EMILE LEGAY have invented a new and useful Electrical Accumulator, (for which they obtained Letters Patent in France for fifteen years, No. 153,393, dated January 27, 1883,) of which the following is a specification.

The elements constituting the electrical accumulator forming the subject of the present invention consist of either tubes, cylinders, blades, bands, or ribbons of lead, fluted, channeled, or grooved, some externally, some internally, and some both internally and externally, as will be hereinafter explained. They may be undulated or spirally twisted and boxed, one within the other, the grooves, flutes, or channels being either straight, curvilinear, zigzag, or inclined at angles varying from thirty to forty-five degrees. These grooves are previously coated with a mastic cement or composition, which they serve to hold, and which consists of any of the sugars, caramels, dextrine, or, by preference, glucose, as it possesses greater reducing properties than glycerine,used in a former patent, and is less costly, and should be diluted to 36 Bauin; these are combined with ten parts of litharge and three parts of platinized carbon, said substances when combined with the carbon constituting an efficient element of the battery. The sulphuric acid usually employed in batteries is replaced by a solution of permanganate of potash or soda, or a solution of any other salt or potash, or permanganate of potash or soda in powder, mixed directly with the oxides above named, can be employed. By this novel arrangement a great number of the blades, tubes, or cylinders, grooved as described, can be used, so that the surface of action is largely increased. These tubes, blades, or cylinders are kept apart by means of either solid or hollow glass or other insulating rings. Each of the tubes, blades, or cylinders is secured separately to one end of the vase containing the accumulator.

It should be observed that in accumulators of this description care should be taken always that the center tube or cylinder, as the case may be, should be grooved outside only, and the last tube, or that one which surrounds the whole, should be grooved internally. The

number of blades, tubes, or cylinders would naturally vary in accordance with the power of the accumulator.

In Figures 1 and 2 of the accompanying drawings an electrical-accumulator of the description herein mentioned, but of small dimensions, is illustrated in vertical and horizontal section.

The apparatus comprises an inner tube or cylinder, a, grooved or fluted externally; then, one, two, or several cylinders, b b, which are grooved internally and externally, and lastly, an outer cylinder, 0, grooved internally. The grooves on each of these tubes or cylinders may be either straight or inclined at an angle varying from thirty to forty-five degrees, as shown, for example, on an enlarged scale, Figs. 4 and 5.

The cylinders a b b 0, one within the other, are suspended by the extension-pieces A B B O to one end of the vase '22, leaving even or unequal spaces between them.

Instead of cylindrical tubes, grooved tubes of any other section can be employed, rectangular, oval, flat, and so forth. These grooved tubes or cylinders may be bent in undulated or other forms, as shown by Figs. 6 and 7. They may be molded or made in any convenient manner.

Fig. 3 shows the tubes replaced by blades Z 1, also grooved, encircling each other, being first coated with mastic in the same manner as the tubes They are separated from each other by glass rings as or other insulating substance.

To prevent the blades unwinding, their ends are fitted with leaden ferrules.

\Ve claim as our invention- In an electric battery, the externall ygrooved tube a, combined with the doubly-grooved tube 11 and internally-grooved tube 0, the said tubes being coated with a mastic of sugar, litharge, and platinized carbon, as described, each tube being secured to one end of the vase '11, substantially as herein shown and described.
